The invention relates to a vehicle stability control method and a vehicle stability control device.The vehicle stability control method comprises the steps that running state parameters of a target vehicle before adjustment are obtained, a target adjustment tire and the target adjustment tire pressure of the target adjustment tire are obtained, then the tire pressure of the target adjustment tire is adjusted to the target adjustment tire pressure, and the target adjustment tire pressure is adjusted to the target adjustment tire pressure; and after the tire pressure of the target adjustment tire is adjusted, the adjusted driving state parameters of the target vehicle are obtained to obtain correction parameters, and finally, the target vehicle is stably controlled based on the correction parameters, so that the vehicle is stable. Compared with the prior art, the method has the advantages that the adhesion coefficient between the vehicle and the road surface is changed by changing the tire pressure so as to improve the stability of the vehicle, a stable control effect is further provided for the vehicle by correcting the parameters, and the adhesion capacity between the tires and the road surface is utilized to the maximum extent to stabilize the vehicle body; meanwhile, vehicle power does not need to be cut off, and the vehicle stability is greatly improved.
本发明涉及一种车辆稳定性控制方法及车辆稳定性控制装置,其先获取目标车辆的调整前行驶状态参数,得到目标调节轮胎以及所述目标调节轮胎的目标调节胎压,再将所述目标调节轮胎的胎压调节至所述目标调节胎压,在调节所述目标调节轮胎的胎压之后,获取所述目标车辆的调整后行驶状态参数得到修正参数,最后基于所述修正参数对所述目标车辆进行稳定控制,使车辆稳定。相比于现有技术,本发明先通过改变胎压的方式改变车辆和路面之间的附着系数以提高车辆的稳定性,并且进一步通过修正参数的方式给车辆提供稳定控制效果,最大程度地利用轮胎与路面之间的附着能力去稳定车身,同时无需切断车辆动力,极大的提高了车辆的稳定性。
